Legrand P312 Residual Current Circuit Breaker with Overcurrent Protection 2P 6A C 30mA Type AC

The Legrand P312 residual current circuit breaker with overcurrent protection (RCBO) is a high-quality 2-pole electrical safety device designed to protect circuits from both overcurrent and leakage currents. By integrating short-circuit protection, overload protection, and residual current detection into a single compact unit, this device ensures comprehensive safety for residential and commercial electrical installations. It is engineered to provide reliable performance and consistent protection for connected equipment and users.

Advantages

The primary advantage of this RCBO is its space-saving design, which combines multiple protective functions into one module, simplifying installation within distribution boards. The device features a 6A rated current and a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents. Its 30mA sensitivity for AC type leakage currents provides essential protection against electric shock and fire hazards, ensuring that the electrical system remains safe and compliant with modern standards.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of individual final circuits
• Preventing electric shock in standard AC electrical installations

When it may not be suitable

This device is designed specifically for AC type leakage currents and may not be suitable for installations where DC components are present, such as circuits connected to certain types of power electronics or solar inverters. It should not be used in environments requiring higher sensitivity or different tripping characteristics than those specified.

Key specifications

• Number of poles: 2P
• Rated current: 6A
• Tripping characteristic: C-curve
• Residual current sensitivity: 30mA
• Leakage current type: AC

How to use

The Legrand P312 RCBO should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a consumer unit or distribution board. Ensure that the supply cables are correctly terminated at the input terminals and that the load circuits are connected to the output terminals, observing the correct polarity and torque settings as specified by the manufacturer.

What to consider before purchase

• Verify that the 6A rating is appropriate for the total load of the circuit
• Ensure the installation environment is compatible with AC type residual current protection
• Check the available space in your distribution board for a 2-pole device
• Confirm that the C-curve characteristic matches the starting current requirements of your connected appliances

Usage recommendations: Regularly test the device using the integrated test button to ensure the mechanical tripping mechanism remains functional. It is recommended to perform this check at least every six months to maintain optimal safety levels.
